    <h1>Working with layers and map contents</h1>
    
    <p>A mapping application can use one or more content sources.
        Each content item corresponds to a service, 
        such as an ArcGIS Server service or ArcIMS service.
        Each source contains one or more map layers. 
        A map layer is a type of data shown on the
        map, such as roads, cities or a satellite image. </p>
        
     <p>If the mapping application allows it, you can view
        the list of the contents of the map, turn on and off layers,
        and examine the symbols for layers.
        </p>
        
    <p>To examine the map contents:</p>
    <ul>
        <li><p>In the <a href="GettingStarted.htm#Console">Console</a>,
            display the <b>Map Contents</b> item, if necessary, by
            clicking the down arrow for Contents
             <img src="images/taskExpand.gif" />. If
            Contents is not present, then this mapping application
            does not allow viewing the contents list.</p></li>
        
        <li><p>When Map Contents opens, only the top-level content items
            are visible. Your content item(s) will probably differ
            from this graphic. </p><p>
            <img src="images/MapContents_1.gif" /></p></li>
        
        <li><p>Click the plus button 
            <img src="images/plus.gif" />
            next to a content item to display the <b>layers</b>
            within it.</p></li>
            
        <li><p>The <b>check-box</b> next to the layer indicates whether
            the layer is currently turned on.</p></li>
            
        <li><p>If enabled, you can click the check-box next to
            the layer name to <b>turn the layer on or off</b>. 
            The map automatically redraws to reflect the
            changes in layer visibility.</p></li>
            
        <li><p>Some layers may not be visible at the current map
            scale (zoom level). These layers are called
            <b>scale dependent</b>. You may need to zoom the map
            in or out to see a particular layer displayed,
            even if its check-box is checked to draw.</p></li>
        
        <li><p>If layers have a plus button 
            <img src="images/plus.gif" />
            next to the name, you can expand the layer
            to display a <b>legend</b> for the layer. The legend
            may display a single symbol or multiple symbols
            for the layer.</p><p>

    </ul>
